My friend, seek a specialist and have your spine and neck(especially) looked into. Sometimes it can take months, or even years, for either of these types of injuries to rear it's ugly head(s).

Did this person run into your trailer chock full of your livelihood? No equipment were damaged? He didn't end up in the same spot as your mower "was"?

i checked the doctors and i'm good, they tell me my bones are perfect or good but i thought differently since i have knee problems but it's heredity i got it from my mom and dad. i'm young and they said my bones are tough. no trailer was involved but he mustang was going 60 and i was in a dead stop when he rear ended me.
